関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fountain solution automatic replenishing device used for lithographic printing such as offset printing. More specifically, the present invention relates to an automatic dampening water replenishing device capable of automatically replenishing a dampening water tank for a lithographic printing press with dampening water adjusted within a predetermined concentration range and facilitating troubleshooting.

る。2. Description of the Related Art Offset printing (lithographic printing) is a printing method that skillfully utilizes the property that water and oil are essentially immiscible. The printing plate surface is composed of a region that receives water and repels oily ink, and a region that repels water and receives oily ink. The former is a non-image region and the latter is an image region.

域のインキ受用性の差を増大させる作用を有している。The fountain solution used in lithographic printing expands the surface chemical difference between the image area and the non-image area by wetting the non-image area, and the ink repulsion of the non-image area and the ink reception of the image area are received. It has the effect of increasing the sex difference.

が用いられる。As such a dampening solution, an additive generally called an etching solution (eg, acidic etching solution, alkaline etching solution, alcohol, etc.), that is, a dampening solution stock solution is diluted with water and usually 0.1 It is used in the range of up to 5% by weight, and various chemicals are usually mixed in the etchant to enable stable printing. The chemicals include, for example, a desensitizing agent for the plate non-image area, a pH adjusting agent, a pH buffering agent, a wetting agent, a chelating agent, an antiseptic agent or alcohol. Moreover, as water, tap water, industrial water, well water, etc. are used.

た水溶液がある。Specific examples of fountain solution generally known in the past include alkali metal salts and ammonium salts of dichromic acid, phosphoric acid or salts thereof such as ammonium salt, gum arabic, carboxymethyl cellulose (CMC). There is an aqueous solution to which a small amount of stock solution containing a colloidal substance such as) is added.

き起こす。However, as described above, since the amount of the dampening water additive such as the etchant is small compared to the large amount of water used, it is difficult to properly control the additive concentration. , Even if some fluctuations occur, the balance between the printing ink and dampening water is likely to be lost, and various printing problems such as dirt, roll accumulation, roller stripping, delay in setting and drying, gloss deterioration, and halftone dot reproduction. It causes deterioration of sex.

のは望ましくないものとなっている。In addition to this, an aqueous solution containing about 20 to 25% of isopropyl alcohol (IPA) was also used as the dampening water, but since isopropyl alcohol easily evaporates, it is difficult to keep the concentration constant and it is expensive. In addition to the need for equipment, the problem of peculiar odor and toxicity makes it undesired to be used alone in the present day when there is high social concern about industrial pollution.

る。Therefore, conventionally, a method and an apparatus for adjusting the additive concentration of dampening water within a predetermined appropriate concentration range have been used and proposed. Usually, the offset printing machine is provided with a dampening water cooling circulation device,
The dampening water is stored in the dampening water tank. Then, one or more stock solutions of dampening water and water are supplied to the dampening water tank to obtain dampening water having a constant concentration. By the way, since the dampening water needs to be appropriate depending on the configuration and performance of the offset printing machine, the composition and concentration of the dampening water are adjusted according to the offset printing machine used. Therefore, depending on the composition of the dampening water, for example,
Offset of 1-liquid system in which one stock solution of dampening water containing all necessary components such as etchant is stored in a stock tank, supplied to the dampening water tank at the time of use, and diluted with water There is also a printing machine. However, in many offset printing machines, it is difficult to stably mix and dissolve all the necessary components of the fountain solution used in one liquid.
Since individual stock tanks may cause precipitation etc., it is difficult to mix them, and components that may cause precipitation, etc. may be added to two or more stock solutions of fountain solution, for example, IPA substitute solution, additives and low concentrations. Concentration IPA or etchant and additives are stored in different stock tanks, and when used, two or more of these stock solutions of fountain solution and dilution water are supplied to the fountain solution tank and used as a mixture 2 Liquid method is adopted.

いものであった。For this reason, conventionally, the concentration of dampening water in both the one-component system and the two-component system is measured by measuring the pH or conductivity of the dampening water in the dampening water tank, or by using a float when using IPA. The density controller was used to keep the density constant, but the accuracy was poor and the accuracy was poor.

A mixing and feeding device is disclosed in Japanese Utility Model Publication No. 56-163535, but neither the amount of water nor the amount of undiluted solution of one kind or two or more kinds is sufficiently adjusted, and the concentration of dampening water is kept constant. It was not enough to adjust.

The non-image area of the plate has a drawback that it is difficult to uniformly wet it, so that the printed matter is sometimes soiled, and considerable skill is required to control the supply amount of dampening water.

３−１０６６９４号に開示している。In order to improve this, the present applicant uses a new fountain solution which is free from toxicity and safety problems and is excellent in workability and stability. Japanese Unexamined Patent Publication No. 3-106694 discloses a compact and inexpensive replenishing device and method capable of stably metering a dampening water tank of a dampening water cooling circulation device.

題があった。This replenishing device not only has excellent physical properties as a fountain solution as compared with the conventional replenisher, but it also provides a dampening solution with a stable concentration with a fairly high accuracy. Since a metering pump is used as the liquid feed pump, and the liquid feed amount is measured by controlling the operating time of the pump, the fluctuation becomes large and there is a limit to further increase the accuracy. Further, since the metering pump rarely causes an idle operation, there is a problem that the accuracy cannot be sufficiently improved.

た。Further, the above-mentioned various devices are provided with a calculating means, a display means, and a calculating means for calculating an integrated flow rate of water and one or more stock solutions of dampening water and a concentration of dampening water calculated from these integrated flow rates. Since it does not have a memory means, if the main power is cut off during a power failure or when trouble occurs with this device or printing machine, the cumulative flow rate of water and dampening water and the concentration of dampening water will not be known. However, there is a problem that it is necessary to remake the dampening water in the dampening water tank from the beginning, and it is difficult to find the cause of the trouble.

いる。Next, the control unit 48 controls the automatic replenishment signal (a).
After a certain delay time of Δt d , for example, 2 seconds has elapsed after the rising edge, the flow rate signal (pulse number) of the water flow rate sensor 18 is checked for a predetermined check time Δt c , for example, 2 seconds (from the rising edge of (a)). The check signal is turned on for checking (for 2 to 4 seconds). This is, for example,
Even if the water is cut off, if water is accumulated in the pipe line 44 near the solenoid valve 20, water flows at the beginning of opening the solenoid valve 20, for example, the first 2 seconds, that is, the transition period, and the flow rate sensor 18 flows. This is because the signal is output, but the flow rate of water immediately decreases and the water flow rate signal (pulse) stops. Therefore, in the present invention, the time of this transient response is set as the delay time Δt d , and it is not used for checking the flow rate such as water interruption.
